La Quinta Columna
La Quinta Columna (English: The Fifth Column) is a Spanish independent research and journalism group founded in 2020, best known for their claim that Graphene Oxide was present in COVID-19 vaccine vials. Led by biostatistician Ricardo Delgado Martín and physician Dr. José Luis Sevillano, the group gained international attention after publishing analysis purportedly demonstrating the presence of undisclosed graphene-based materials in vaccine samples. Their work sparked significant debate within both alternative research communities and mainstream scientific circles, and contributed directly to wider investigations into the contents of COVID Vaccines and the emerging field of Intra-Body Nano Network theory.
Background and Founding
La Quinta Columna was established in Spain in late 2020, initially as a commentary platform responding to the COVID-19 Pandemic and the governmental response to it. The group operated primarily through online broadcasts, social media channels, and their website, building an audience across Spanish-speaking countries and eventually attracting international attention through translation networks.
Ricardo Delgado Martín, the group's primary spokesperson and strategist, holds a background in biostatistics and biological analysis. Dr. José Luis Sevillano is a practising physician who contributed medical interpretation and clinical context to the group's findings. Together, they positioned themselves as citizen researchers willing to ask questions they believed were being suppressed by mainstream institutions.
The name "La Quinta Columna" is a reference to a covert group operating within a larger body — in this case, implying that they were exposing an agenda operating from within the institutions trusted to protect public health.
The Graphene Oxide Claim
In June 2021, La Quinta Columna published what became their most widely circulated claim: that Graphene Oxide had been identified in samples from the Pfizer-BioNTech COVID-19 vaccine. Their initial report alleged that graphene oxide constituted the majority of the contents of certain vaccine vials — a claim that, if accurate, would have represented a profound undisclosed ingredient in a product administered to billions of people.
The group collaborated with Dr. Pablo Campra, a materials scientist at the University of Almería in Spain, who produced a technical report in late 2021 using optical microscopy and micro-Raman spectroscopy to analyse the samples. Campra's report, published through the platform Corona2Inspect, claimed to identify structures consistent with graphene and reduced graphene oxide in the biological material examined.
Methodology
The analytical techniques employed included:
- Optical microscopy — to visually identify unusual structures and morphologies within the liquid samples
- Micro-Raman spectroscopy — a technique that can identify carbon-based nanomaterials through their characteristic spectral signatures (specifically the D and G bands associated with graphene)
- Transmission Electron Microscopy (TEM) — used in follow-up analyses to image nanoscale structures
Campra's methodology and findings were documented in a series of technical reports which the group circulated widely. Supporters argued that the Raman spectral data was compelling; critics argued that the sampling chain was unverified, and that similar Raman signals can arise from other carbonaceous contaminants.
Carbon Quantum Dots and Graphene Quantum Dots
A significant dimension of La Quinta Columna's analytical findings — particularly those arising from Transmission Electron Microscopy (TEM) imaging and micro-Raman spectroscopy — is that some of the structures identified display characteristics consistent not only with bulk graphene oxide, but also with Carbon Quantum Dot material and graphene quantum dots (GQDs).
Carbon quantum dots are nanoscale carbon-based particles, typically between 2 and 10 nanometres in diameter, which exhibit distinctive photoluminescent properties and characteristic Raman spectral signatures that overlap significantly with those produced by graphene-family materials. Graphene quantum dots are a specific subset — essentially nanoscale fragments of graphene sheets — that retain the D and G band Raman signatures associated with graphene while also exhibiting quantum confinement effects due to their extremely small size.
Researchers examining the data produced by La Quinta Columna and Dr. Pablo Campra have noted that the spectral profiles observed in the Raman analyses are consistent with a mixture of graphene-family materials that could plausibly include both reduced graphene oxide and carbon quantum dot or graphene quantum dot fractions. This is significant for several reasons:
- Carbon quantum dots and graphene quantum dots are already used in legitimate biomedical applications as drug delivery carriers and fluorescent imaging agents
- Their extremely small size means they can penetrate cellular membranes and potentially cross the blood-brain barrier
- Their electromagnetic and photoluminescent properties make them theoretically suitable as components of a Biosensor or Intra-Body Nano Network substrate
- Their presence would not be detectable through standard optical microscopy, potentially explaining why some analyses failed to identify unusual structures while others did
This intersection between the graphene oxide hypothesis and carbon quantum dot research has been noted by researchers working on Graphene in Vaccines and Nanoparticles in Vaccines, who argue that the distinction between these closely related carbon nanomaterial classes may be less important than the overarching question of whether any undisclosed conductive carbon nanomaterials were present at all. The Corona2Inspect platform, through the work of Mik Andersen, also addressed this overlap — exploring how quantum dot-scale graphene fragments could contribute to the electromagnetic properties of the broader nanonetwork proposed in their theoretical framework.

The Campra Report Connection
One of the most technically significant outputs arising from La Quinta Columna's research campaign was the formal scientific report produced by Dr. Pablo Campra, a materials engineer and professor at the University of Almería. His 2021 report — Detection of Graphene in COVID-19 Vaccines — represented a direct response to the questions that La Quinta Columna and Ricardo Delgado had raised publicly about the undisclosed contents of COVID Vaccines vials.
La Quinta Columna were among the very first groups globally to publicly allege the presence of graphene oxide in vaccine formulations. Their broadcasts and publications in mid-2021 preceded and directly prompted calls for independent scientific investigation. It was within this research community that Campra was approached to apply formal materials science methodology — specifically micro-Raman spectroscopy — to the samples in question. The resulting report provided the first structured technical documentation of spectral signatures that the author characterised as consistent with graphene-family materials.
Role of Mik Andersen and Corona2Inspect
A crucial figure in the wider dissemination and technical elaboration of Campra's findings was Mik Andersen, a Danish independent researcher operating under the platform name Corona2Inspect. Andersen provided detailed supplementary analysis of the hydrogel medium described in Campra's report — examining the physical and chemical properties of the aqueous matrix in which the putative graphene structures were suspended.
Andersen's Corona2Inspect platform became a key node in the international network of independent researchers examining vaccine contents. His work explored how a hydrogel or polymer-based medium could serve as a carrier matrix for conductive nanomaterials — including graphene oxide, reduced graphene oxide, and potentially Carbon Quantum Dot fractions — and he developed theoretical frameworks connecting the observed structures to the broader concept of an Intra-Body Nano Network — a proposed internal mesh of nanoscale components capable of receiving and transmitting electromagnetic signals within the human body.
The collaboration between La Quinta Columna, Campra, and Andersen represented one of the more structured examples of distributed independent scientific inquiry during the COVID-19 period, with each contributor bringing a distinct disciplinary lens:
- Ricardo Delgado — biostatistics, public communication, and sample coordination
- Dr. Pablo Campra — materials science, spectroscopic analysis, formal technical reporting
- Mik Andersen — theoretical nanonetwork modelling, hydrogel medium analysis, dissemination through Corona2Inspect
Key Findings of the Campra Report
The final version of Campra's report — available as a PDF document — outlined the following principal claims:
- Micro-Raman spectroscopic analysis of COVID Vaccines samples produced spectral peaks at positions consistent with the D band and G band characteristic of graphene and reduced graphene oxide
- Optical microscopy revealed structures morphologically similar to graphene sheets and crumpled graphene formations
- TEM imaging identified nanoscale structures whose size, morphology, and spectral characteristics were assessed as potentially consistent with graphene-family materials, including particles in the size range associated with carbon quantum dots and graphene quantum dots
- The presence of these structures could not be accounted for by the publicly disclosed ingredients of the vaccines
- The author called for urgent replication studies by independent certified laboratories operating under verifiable chain-of-custody conditions
Campra was explicit that his report constituted a preliminary investigation rather than a definitive proof, and that formal replication was required. He maintained, however, that the spectroscopic evidence was sufficiently consistent with graphene-family materials — potentially encompassing both bulk graphene oxide and quantum dot-scale carbon nanomaterial fractions — to warrant serious scientific investigation.
Significance for Graphene in Vaccines Research
The Campra Report became a foundational reference document across the independent research community examining Graphene in Vaccines. It was cited by researchers including Dr. Ana Maria Mihalcea in their own work on anomalous structures in the blood of vaccinated individuals, and it provided the evidentiary basis for subsequent discussions connecting graphene's electromagnetic properties to the theoretical substrate of biosurveillance and neural interface technologies.
The report also intersected with broader concerns articulated by researchers working on Self-Assembling Nanostructures, who noted that the described graphene-based formations — including potential Carbon Quantum Dot and graphene quantum dot components — could theoretically self-organise under electromagnetic stimulation into functional network components consistent with the Internet of Bodies infrastructure described in emerging technology literature. The potential presence of quantum dot-scale particles is particularly relevant to Nanoparticles in Vaccines research, given that such particles are known to exhibit unique optical and electronic behaviours not present in their bulk counterparts.

Link to 5G and Electromagnetic Activation
A central pillar of La Quinta Columna's theoretical framework is the proposition that graphene oxide within the human body can be activated or excited by electromagnetic frequencies — specifically those associated with 5G networks. According to this model, graphene oxide, being an excellent electromagnetic radiation absorber and conductor, could function as an antenna or receiver when introduced into biological tissue.
The group proposed that this interaction could explain a range of phenomena they attributed to vaccine recipients, including unusual electrical conductivity in the blood, neurological symptoms, and the formation of Self-Assembling Nanostructures visible in blood samples. They further suggested that the graphene component — potentially including Carbon Quantum Dot fractions with their distinctive quantum electronic properties — could interface with cellular biology to form the substrate for an Intra-Body Nano Network — a proposed internal communications mesh that, theoretically, could receive external signals and monitor or influence physiological processes.
This hypothesis connected their work to broader discussions around the Transhumanist Agenda, including concerns raised by other researchers about undisclosed Nanotechnology in public health interventions.
International Reception
La Quinta Columna's initial report spread rapidly through alternative media networks in 2021. The work was translated into English, French, German, Portuguese, and other languages within days of its publication. Several high-profile alternative researchers and commentators cited the group's findings as confirmation of suspicions about undisclosed ingredients in the COVID Vaccines.
Researchers such as Dr. Ana Maria Mihalcea and others working on Self-Assembling Nanostructures in blood samples referenced the graphene oxide hypothesis as a possible explanatory mechanism for anomalous structures they observed. The Spanish group's findings became a significant node in the international network of independent COVID vaccine research, with some researchers specifically flagging the potential overlap between graphene oxide and Carbon Quantum Dot material as an area warranting deeper investigation.
The group also received attention from broader platforms covering topics including Neuroweapons, Brain-Computer Interface technologies, and the Internet of Bodies, as commentators drew connections between graphene's properties and surveillance-capable nanotechnology.
Spanish-Language Impact
Within Spain and Latin America, La Quinta Columna developed a substantial following. Their broadcasts regularly attracted tens of thousands of live viewers, and their Telegram channels accumulated large subscriber bases. Some Spanish-speaking physicians and scientists publicly supported their call for independent investigation, though few credentialed researchers were willing to formally endorse the full scope of their conclusions.
Mainstream Scientific Response
Mainstream scientific and regulatory institutions largely rejected or ignored La Quinta Columna's graphene oxide claims. Responses included:
- Reuters and AFP Fact-Checks — classified the graphene oxide claim as "false", citing statements from Pfizer and independent laboratory analyses that found no graphene oxide in the vaccine formulations
- Vaccine manufacturers — Pfizer and other producers formally denied that graphene oxide was present in any form in their products
- Academic reviewers — pointed out that the Raman spectroscopy results in Campra's report were not conclusive, arguing the spectral peaks could correspond to other organic or carbonaceous materials — including, critics noted, carbon quantum dot contaminants — and that the chain of custody for the analysed samples had not been independently verified
However, some researchers noted that mainstream rebuttals primarily consisted of manufacturer denials and did not produce independent peer-reviewed spectroscopic analyses of the specific samples in question. Critics of the rebuttals argued that proper scientific protocol would require direct testing of unopened vials with verified lot numbers under independent laboratory conditions — a process that was not publicly documented at the time. They further observed that the potential presence of carbon quantum dot material was not specifically addressed in any official rebuttal, despite its overlapping spectral signature with graphene oxide.
Dr. Pablo Campra and the Almería Reports
Dr. Pablo Campra played the most technically significant role in La Quinta Columna's research output. His academic background in materials engineering gave the group's claims a degree of technical credibility that distinguished them from purely anecdotal reports. His official reports — released through the Corona2Inspect platform — provided the raw spectroscopic data that formed the evidentiary backbone of the graphene claim, and addressed the possibility that the identified carbon nanomaterials could include quantum dot-scale graphene fragments alongside larger graphene oxide sheets.
Campra subsequently released multiple versions of his technical report, refining his analysis and responding to criticisms. He maintained that the Raman spectral evidence was consistent with graphene-family materials and called for official replication studies by independent certified laboratories. These calls were not taken up by any government regulatory body publicly.

Ongoing Research Activities
Beyond the initial graphene oxide report, La Quinta Columna continued to produce research content throughout 2022, 2023, and into 2024. Their ongoing work included:
- Analysis of anomalous structures in the blood of vaccinated individuals, contributing to the wider discussion around Self-Assembling Nanostructures
- Commentary on the potential role of Graphene and graphene derivatives — including carbon quantum dot and graphene quantum dot fractions — as components of a proposed Intra-Body Nano Network
- Investigation of Lipid Nanoparticles and their potential to carry undisclosed payloads, including quantum dot-scale nanomaterials
- Examination of findings documented through Nanoparticles in Vaccines research, particularly regarding sub-10nm carbon nanomaterial fractions detectable only through TEM and advanced spectroscopy
- Discussion of biosensor and bioelectronic possibilities enabled by conductive nanomaterials in biological tissue, with reference to the known properties of carbon quantum dots as fluorescent biosensing agents
- Ongoing broadcasts and educational content linking their findings to broader Nanotechnology and Biosurveillance concerns
The group has also addressed the legal and ethical dimensions of their claims, advocating for criminal investigations into what they characterise as unlawful medical experimentation on uninformed populations — invoking the principle of Bodily Autonomy and informed consent in medical practice.
Significance in Alternative Research
Regardless of the ultimate resolution of the graphene oxide debate, La Quinta Columna occupies a historically significant position in the landscape of independent COVID vaccine research. They were among the first groups to systematically apply materials science analytical methods to vaccine samples and to publicly publish the results. Their methodology, however contested, pushed the conversation beyond anecdote and into technical territory that required technical rebuttals rather than simple dismissal.
Their work has been cited extensively in:
- Independent journalism covering COVID Vaccines and undisclosed ingredients
- Research into Graphene in Vaccines, Graphene Oxide, and Carbon Quantum Dot nanomaterial identification
- Studies on Nanoparticles in Vaccines and the challenge of detecting sub-visible nanoscale components in pharmaceutical formulations
- Theoretical frameworks around the Internet of Bodies and biological surveillance
- Discussions of potential links between public health policy and the Transhumanist Agenda
